The stories in Jette & Jo books and songs are original written works created by humans. Lyrics, melodies, and book storytelling are written by the creative team.
Jette & Jo is co-created by sisters Chel Hill and Kelli Hill, with support from their family and collaborators. The books are narrated by their mother, Juana Hart. The characters are voiced by Kelli’s daughters.
Chel Hill is a songwriter and creative founder who believes stories and music can help children make sense of big feelings. She serves as the primary creative lead behind Jette & Jo. Chel also created the original animations and visual storytelling that introduced Jette & Jo in its early stages. Kelli Hill is an Emmy® and Clio Award–winning live events producer whose experience in creative leadership and high-impact storytelling contributes to the vision and execution of Jette & Jo.
Together, Chel and Kelli created Jette & Jo to offer gentle, thoughtful books and songs that support confidence, courage, and emotional expression — especially for children who feel deeply, quietly, or intensely.
